> RateLimiting for FileSystem
> ---------------------------
>
> Key: FLINK-9560
> URL: https://issues.apache.org/jira/browse/FLINK-9560
> Project: Flink
> Issue Type: Improvement
> Components: FileSystem
> Affects Versions: 1.5.0
> Reporter: Etienne CARRIERE
> Priority: Major
>
> *Pain*: On our system, we see that during checkpoint , all the bandwidth is
> take to send the checkpoint to object storage (s3 in our case)
> *Proposal* : After the creation of some limitation on Filesystem (mostly
> number of connections with the tickets FLINK-8125/FLINK-8198/FLINK-9468), I
> propose to add ratelimiting "per Filesystem" .
> *Proposal of implementation* : Modify LimitedConnectionsFileSystem to add a
> ratelimiter on both Input and OutputStream.
